1. The Fairy Performance Assessment: Measuring Computational Thinking in Middle School Linda Werner, UC Santa Cruz Jill Denner, ETR Associates Shannon Campe, ETR Associates Damon Chizuru Kawamoto Funded by the NSF grant DRL-0909733

2. Project Overview Storytelling Alice & Alice 2.2 Elective technology classes 325 middle school students 311 completed assessment Solo or programming pairs ~20 hours

3. Assessment Design Story-narrative Fixing faulty program & adding functionality Motivating Post only Individually completed ~30 minutes to complete Instructions delivered via characters & print

4. Measuring Computational Thinking Three tasks to measure: Algorithmic thinking Abstraction & Modeling

5. Alice “Fairy” world

6. “Resize” Task Make pressing the up arrow work right and return LeafFlame to his original size. Challenges student to: Understand events Recognize faulty event handler Think algorithmically Repair faulty method

7. Faulty code

8. Partial points

9. Contributions Student transfers knowledge Motivating to students Range of computational thinking Modified for other programming environments

10. Still to come… Scratch assessment Solo/pair programmers; girls/boys Measuring aspects of computational thinking Learning analytics
